Answer:
nickels = 12
quarters = 9
Step-by-step explanation:
Let number of quarters be "q", and
number of nickels be "n"
Nickels are worth $0.05 and Quarters are worth $0.25
Since all of them are worth 2.85, we can write:
0.25q + 0.05n = 2.85
Also, we know, there are 3 more nickels than quarters, so we can write:
n = 3 + q
Now, we can substitute equation 2 into equation 1 to get:
Now, we solve for q:
There are 9 quarters.
We know n = 3 + q
So,
n = 3 + 9
n = 12
There are 12 nickels
10 rows= 12 mins
there's 25 rows in all so break it down into 10, 10, and 5 to make it more simple
12+12= 24 minutes for 20 rows
since you only have 5 rows left (which is half of ten), you divide the 12 by two as well.
12mins/2= 6 minutes for 5 rows
24mins+6mins= 30 minutes
answer: It will take 30 minutes to knit 25 rows

Step-by-step explanation:
● 5/2 is 2.5 so just divide the space between 3 by 2
● for 1/3 divide the space between 0 and by 3
Answer:
6⋅6⋅6⋅6
Explanation: The exponent refers to the number of times a number is multiplied by itself. 6^4 represents that 6 is being multiplied 4 times.
Base ⇒ 6
